Just popping back to add a quick observation on all of this 'police state' business: The sheer ludicrousness of most claims (and Henry Porter on Damian Green really does just show how wind-up-and-go this rubbish is) masks a more serious charge.
In the absence of much by way of yer actual totalitarianism, it seems to me that most of it is less a complaint about any actually existing illiberality, and more the question of how apparatus is being put in place that could be abused by a future government. None of this stops current ministers being written up as though they were in the KGB.
That a police state is being constructed in the wings, and once it's been completed, it can be wheeled on centre-stage so that someone can crank it up. The upside to all of this is that Henry Porter does, indeed, get arrested and has his fingernails pulled out.
The downside is that Parliament would jump in and reverse unacceptable legislation (as it did, unwisely in my view, on the 'right' to protest outside Parliament).
The thing about these 'thin end of the wedge' arguments is that you'd take them seriously if they weren't written from the thick end of it.
